    The probability that none will have high blood pressure is 0.0281

    Step-by-step explanation:

    The correct question is as follows;

    Twenty percent of Americans ages 25 to 74 have high blood pressure. If 16 randomly selected Americans ages 25 to 74 are selected, find each probablility. a. None will have high blood pressure

    This is a binomial problem. We shall solve in that line

    The probability of success is 20% or 0.2 [ (Americans ages 25 to 74 have high blood pressure) ] p = 0.2

    The probability of failure q is thus 1-p = 1-0.2 = 0.8

    The probability of none is thus;

    P (X = 0) = 16C0 p^0 q^16

    = 16C0 * 0.2^0 * 0.8^16 = 0.0281
